Ralf Schemmann runs the Live Mapping series on the ProFantasy Facebook page, where he uses CC3+ and add-ons to create maps within an hour live on video. The videos are then archived on YouTube where you can still view them at your leisure.
Joshua Plunkett takes new users on a tour of Campaign Cartographer 3+ in this video tutorial. You can view many more execellent tutorials on his YouTube channel.
CC3 Video Tutorials
Joseph Sweeney (www.storyweaver.com/mastermapping) takes you through creating overland maps with CC3 and using sheet effects to enhance them. Originally published in the Cartographer's Annual 2008, these tutorials are simply too useful to not make them generally available.
